datasource.AbstractContourDataSource.AbstractContourDataSource
Abstract datasource that supplies data for contour. Data are supplied as a set of grids. Contour building algorithm calls 'Query' method to get the enumerator that enumerates set of grids appropriate for given model rectangle and model-to-device transformation. Contour building algorithm calls 'LoadGrid' on enumerator to load grid into memory and get access to its data.
